MACHINE FoR MAKING LUBRICATING MEANS OR VEHICLE sPRING's.

Application filed October 20,1821. Serial Nb. 509,211.

This invention has to do with mechanism for making lubricating means or strips for insertion between the leaves of vehicle springs, such as disclosed in Letters Patent No. 1,37 8,159 granted to me May 17, 1921, the chief object of the invention being to pro vide a practical and efiicient mechanism for use in manufacturing such lubricating means or strips automatically and in a rapid and inexpensive manner. To these and other ends the invention resides in. certain improvements and combinations of parts all as will herein-after be more fully described, the novel features being pointed out in the claims at the end of the specification.

lVhile-the present invention .is capable of application to a variety of uses the embodiment disclosed by way of illustration in the present instance is shown as applied to the use of manufacturing the spring lubricating or greasing means set forth in the above Letters Patent. Such means comprises, briefly, a pair of complementary, perforated strips of material laid one against another with an interposed layer'or coating of any suitable lubricating medium or grease the composite strip thus formed being cut into lengths suitable for insertion between the leaves of vehicular and similar springs for conveniently lubricating the same as well understoodin the art. The complementary strips for the article are preferably perforated in the manner describedin the said patent and such strips maybe advantageously formed" and perforated by media nis'm such as disclosed in my pending ap-' plication for patent Serial N'o.500,297 filed September 13, 1921. The machine of the present invention may be advantageously employed in conjunction with a machine such as disclosed in said application for subsequently combining the perforated strips with an interposed application of lubricant of any suitable material being rotated to drive the web by means of pulley 17:, F igures 3 and 7, rotatably fitted on the end of one of the trunnions of the roll .15. This pulley is formed with a friction clutch surface 18 against which bears a disc 19 of leather or other suitable material on the other side of which is a metal disc20. The

latter is pressed toward the pulley by means of a coiled spring 21 the tension of which'is adjusted by means of a nut 22 on theendof the roll trunnion. This provides a yield'able drive adapted to slip'an'd prevent: injury to the parts in case the machine should become obstructed in any way, and also provides in a simple manner for allowing the pulley to run idle if desired.

The complementary perforated strips used to form the completed article are prefer ably of a porous or absorbent character of paper and'are' utilized in the form of a pair of rolls indicated at 23and 21%, Figure 1. Theserolls aresupported on reel means carried by the uprights 12 and 13 respectively and comprising rotatable spools the cores of which are shown at 25 and 26., The strip 27 from roll 23 is preferably'led upwardly over the roller 14:. and theforward end; of the belt 16 the upper reach of which is supported by means of a bed or table28 carried by the frame of the machine which is provided also with side guide rails 29, as shown. Strip 2? is supported, guided and fedby the web, passing ofl the rear endof the latter as described hereafter. Adjacent the center and above the upper reach of the web is a roller having its endsrotatably supported in vertical slots 31 in the side rails 29. The roller is pressed yielding downward against strip 27 on the web by means of straps 32, Figures 1 and 4, which engage the trunnions of the roll and are pulled downwardly by means of springs 33 fixed to the frame and adjustably fixed to the straps by means of a set screw 34 carried by cross bar 35 connecting the lower ends of the straps.

The other perforated strip 36 is led from its roll 2% around and under the roller 30 which therefore serves to bring the strips together with their surfaces in contact with each other. As will presently appear, the

.roller bears upon the strip only with sufficient force to bring them fully into contact with each other and theinterposed lubricant, the pressure of the roller bemg adgusted by "the means alread described.

A source of lubricant is provided having means for applying the same between the strips 27 and 36, 1 This lubricant source may have anysuitable form, being shown in the present instance as a container 37 supported above the forward end of the machine in a frame carried by means of standards 38, the container. being connected with a larger source ofsupply if desired by means of a pipe 39. A delivery tube 40 having a valve ll leads downwardly from the container adjacent the upper surface of strip 27, being I provided with a suitable distributing head or nozzle 42 for applying a layer or coating of lubricant to the central portion of the surface of strip 47 as indicated at 43, Figure 3. It is apparent from the above description that as strip 27 is fed rcarwardly into contact with strip 36, the applied lubricant is carried between the strips and tends to cause them to adhere to each other, and the strips thus assembled are fed rearwardly together as one to the rear end of the web. The appropriate quantity of lubricant is obtained by regulation of the valve 41.

The strips thus united and supplied w1th lubricant pass from the supporting and feeding web 16 toward the rear end of the ma chine where the latter is provided with severing means for cutting the combined strips into suitable lengths. To this end the frame comprises a post 4411 having at its top a pair of side standards 45. These standards are formed on their inner sides opposite each other with vertical slots 4.6, Figures 5 and 7 at the bottoms of which'and in a corresponding slot in the top of post 44; is supported a fixed cutting element or knife blade 47 having a cutting edge 48 at its top. Sliding in its ends in the top portions of the slots 46 of the side standards is an upper cutting element or knife blade 49 having a detachable cutting edge portion 50 which may be removed for convenience in sharpening the same. The cutting edge 50 is preferably inclined as shown at Figure 7 for facilitating shearing action with the cooperating blade 48, these blades being located substantially in alignment with the upper reach of the feeding web 16 and the work strips. Fixed to the top of the cutting blade 49 as by means of screws 51 is the transversely extending end of a rod 52 which is bent at one side of the blade to extend downwardly parallel therewith as at 53. The lower end of this rod is turned laterally as at 54c and pivotally connected with an end 55 of a lever 56 pivoted at 57 on the frame. The opposite end of the lever carries a'stud 58 disposed for engagement with the periphery of an eccentric or cam 59 fixed on the outer end of one of the trunnions of roll 15 of the feeding web. This cam is formed with a depression having a radial side 60 and an opposite side 61 which is curved for gradual cooperation with stud 58 of the lever. At 61 are a pair of springs fixed to post 44 and to rod 52 and the upper blade for moving the latter downwardly and maintaining stud 58 in cooperation with cam 59.

It is apparent from this construction that as roller 15 is rotated by the means already described to feed the strips of material, cam 59 is also rotated and, by reason of the shape of its outline, causes lever 56 to oscillate in such a manner that the upper cuttingblade is allowed periodically to drop sharply under actuation of springs 61 to cutthe strips into lengths the blade being raised again practically instantaneously so that there is substantially no obstruction of the feeding of the strips between the cutting elements. The latter being thus operated by connection with the eccentric means actuated by the feeding roll 15, the periodic operation of the cutting elements is synchronized with the feeding of the material, or in other words, is timed to cut the latter into the desired predetermined lengths.

Means are provided for maintaining the combined strips taut between the rear end of the feeding web and the cutting elements and for presenting the strips to the-latter to facilitate the ellicient operation of the same, comprising preferably a pair of rolls 62 and 63 journaled at their ends in vertical slots 64 in the side standards -15. disposed one above another for eng gement with opposite sides of the combined strips, the upper roll being pressed lightly toward the lower roll at each end by moans comprising an adjusting screw 65 and a block 66 ad justed by the screw and having resilient means of any suitable form for engagement with the roll trunnions. The trunnions of these rolls are provided at one end with intermeshing gears 67 and 68, Figure 7, and

'lhese rolls are the lower roll carries at its other end a pulley 69 for driving both rolls. The latter have their surfaces formed with circumferential grooves as shown which prevent the expressing of the lubricant at the sides of the strips and which also cooperate with means for stripping the material from the rolls. The stripping means comprise preferably a series of fingers 70 carried by a stationary cross bar 71, Figure 5, which extend into the grooves of the upper roller 62. A series of curved fingers 72 supported by the lower cutting element 4-7 extend into the grooves of the lower roller 63 and partly around the latter. These fingers effectively prevent the strips from adhering to the surfaces of the rolls so that they are inevitably fed by the latter between the cutting elements. The driving means for these rolls is preferably designed to rotate them at a speed in excess of that of the strips so that they tend to draw the latter taut from the rear-end of the feeding web and direct the strips between the cutting elements. A shelf 73 in rear of the lower cutting element receives the lengths of material and discharges them into any suitable receptacle.

Figures 8 and 9 show the strips as combined with the lubricating material therebetween. In starting the machine the complementary strips are preferably associated with their rows of perforations in alternating or staggered relation as shown, sothatthe openings for the escape of the lubricant occur alternately on opposite sides of the completed strip or tape. The strips are maintained in spaced relation with each other to provide lubricant holding space by means of the inturned tops 74, as described. in said Letters Patent.

ln operation, the rolls of the component strips having been placed on their respective reels, and the ends of the strips having been led in the proper paths through the machine, the means for driving the feeding web and the rolls 62 and 68 are put in operation and the supply of lubricant is turned on. The machine then automatically feeds the complementary strips, which are provided with lubricant and laid lightly one upon another 011 the supporting and feeding web. From the latter the strips thus combined are carried by rolls 62 and 63 between the cutting elements the upper of which is operated in time conjunction with the feeding mechanism and cuts the material into suitable lengths. As apparent from the description the machine is simple, practical and eflicient in construction and arrangement, operating automatically to produce the article in a rapid and inexpensive manner.
